That rules out an errant "rotate" command signal as the root cause.

We are using 6 inch andyMark wheels (big metal ones).

Check all the rollers on each wheel. Do they all spin freely? Or are some "dragging" somewhat? Do all the rollers have the same amount of axial free play, or is there a lot of variation?
Also, how difficult would it be to swap the hot motor with one on the other side, and see if the problem follows the motor or stays on the same side?

We are implementing a gyro and shaft encoders to solve the problem. I just don't know where to plug the gyro in from teleop.vi

The only place I know of to "just plug in" the gyro in LabVIEW is in
the VI for 3 DoF (mec or omni) drive. But this gives you field-centric joystick control - it does not prevent rotation.
If you want to use the gyro to help minimize rotation while strafing, that can be done. I could post some C pseudo-code if that would be helpful - or maybe a LabVIEW guru could post a LabVIEW picture.
